Survey and Identification of Plant Parasitic Nematodes on Faba bean Crop in Ethiopia

Abstract

A survey was conducted to determine the types, frequency and population of plant parasitic nematode genera associated with the soils and roots from the rhizosphere of faba bean, during the growing season of 2018-2019. One hundred twenty composite soil samples were randomly collected where a modified Baermann technique for plant parasitic nematode extraction was applied. Faba bean crop grown within two regions i.e., Oromia and Amhara revealed the presence of six nematode genera i.e., Pratylenchus, Rotylenchulus, Tylenchoryhnchus, Xiphinema, Ditylenchus and Tylenchus were detected. The most dominant nematode genera were xiphinema followed by Ditylenchus with 12% and 7% of occurrence respectively. Xiphinema was considered as the widely distributed pest of the faba bean crop as it was associated within all survey regions. The study encourages more research work to establish the economic importance and the management of the reported nematode pests.
